CASTING-MACHINE Specification of Letters Patent.

Patented Feb. 4, 1908.

Application filed December 4,1906. Serial No. 346227.

To all whom it may concern:

Be it known that I, ARTHUR L. WALKER, a citizen of the United States, residing at Dongan Hills, in the county of Richmond, Staten Island, State of New York, have invented a new and useful Casting-Machine, of which the following is a specification.

My invention relates to improvements in casting machines.

My object is to provide improved means for casting wire bars, ingots, anodes and the ike.

My invention comprises improved means for supporting the molds and for securing the same in position so that they will not sag and so that they may readily be removed and replaced by molds of different size.

My invention also comprises improved means for operating the mold supporting means so as to discharge the bars or ingots cast therein and so as to return the mold again to the operative position.

Referring to the drawings :-Figure 1 is a plan view of my device. Fig. 2 is a vertical section on line 2, 2 of Fig. 1. Fig. 3 is a vertical cross-section 011 line 3, 3 of Fig. 1. Fig 4 is a vertical cross-section on line 4, 4 of Fig. 1. Figs. 5, 6, 7 and 8 are end elevations showing the tripping device in different posi tions.

Similar numerals refer to similar parts throughout the several views.

My improved structure comprises the central revolving piece 15, to which is secured the radiating arms 16 connected at their outer ends by the cross bars 17, and near their inner ends by the cross bars 18. These arms may be of any suitable number and set at any required angle with respect to each other, to suit the size of molds desired to use. The structure thus formed is further braced by a series of tie rods 29 extending from the top of member 15 to cross-bars 17. Upon cross bars 17 and 18 are trunnioned the mold shown as provided with four slots and is therefore capable of holding four molds. The number of slots may of course be varied to suit the requirements. As the clamping members 25 are movable along the slots 27, it is obvious that molds of different length may be secured to the plate 19. Longer molds than those shown in solid line, are indicated in dotted lines at 13 and 14 in Fig. 1. Set screws 28 may also be used to add to the security of engagement between the lugs 21 and clamps 25 and molds 23. The trunnions 30 and 31 of mold plate 19 are placed a little off the center say one-half inch so that in the horizontal position one side of the mold. plate 19 will rest on a lug 32 extending from arm 16. That is to say looking at the mold and supporting plate as shown in Fig. 3 the side to the left of the trunnions being the longer side, will rest by gravity on lug 32. These lugs 32 are so proportioned that when the mold plate 19 is inverted as shown in Fig. 4, the heavier side will be to the right of the trunnions and the lower outside edge of the furthest mold 23 to the left of the trunnion, will engage with the outer edge of lug 32, and will be held in said position by gravity until the mold plate is again actuated.

As a convenient means for inverting the molds and returning them to normal position after they have discharged their castings, I provide the structure shown in Figs. 1, 5, 6, 7 and 8 which consists in providing the two arms 33 and 34 on the outer trunnion 30 of each mold plate. I also provide the two stationary rods or fingers 35 and 36.

The operation of this device is as follows: Assuming that the molds start in the operative position as the four are shown which are in alinement with the four-lipped ladle in Fig. 1, the metal is poured by this ladle into said four molds and the structure is then rotated to bring another set of molds in line with the ladle when the operation is repeated. As the molds which have been filled move with the revolving structure in the direction indicated by the arrow in Fig. 1, the arm 34 comes into engagement with the finger 35 as shown in Fig. 5. This causes the mold plateto turn with its molds into the position shown in Fig. 6 from which it is obvious that the mold will fall by gravity into the position shown in Fig. 4 and will be held in such position until, by a further rotation of the rotating structure, the arm 33 encounters the finger 36, as shown in Fig. 7, causing the mold plate and molds to turn into a position shown in Fig. 8 from which position it is obvious that the structure will fall by gravity into the initial position as shown in is stated above, my device is especially adapted for casting wire bars, ingots, anodes and the like, and my purpose is to provide improved adjustable means for securing, and means for supporting the molds of difi'erent sizes, so that the same may readily be removed, and also so as to prevent the sagging of the molds, which has been the cause of trouble in machines now in use in making wire bars, where the molds sag, due to their great length between supports. By the means above described I am enabled to use molds of different lengths and to change said molds quickly; and, in that the mold or mold supporting plates prevent the sagging of the molds, not nearly so much copper need be used in making said molds, and consequently not so much metal need be tied up thereby.
